使python重复一个字符串，直到输入Yes或yes [英] Make python repeat a string until Yes or yes is inputted

问题描述

是的，我知道已经有一篇文章介绍了这一点，但是当我阅读它时，它没有帮助，所以请不要将其标记为重复.

Yes I know that there is already a post covering this, but when I read it, it didn't help so please don't mark this as a duplicate.

我想编写一个程序，询问用户是否需要建议，如果他们输入否"或否"，我希望它重复问题，如果他们输入是"或是"，我希望它打印建议.我希望它包含一个 while 循环

I want to write a program that asks the user if they want advice and if they input "No" or "no" I want it to repeat the question and if they input "Yes" or "yes" I want it to print the advice. I want it to include a while loop

我曾尝试自己编写它，但无法使其正常工作.

I have tried to write it myself but I can't get it to work correctly.

有人知道吗?

来自 3.4 注释的代码 -

Code from the comment for 3.4 -

def doQuestion(question, advice):
reply = ("no")

while reply  == "no":


print (question)





reply = input("Do you need some advice? ").lower()





if (reply == "yes"):


print ("Always listen to your IT teachers") 



 doQuestion("Do you want some advice?","Always listen to your IT teachers")

推荐答案

以下内容将持续检查用户是否需要有关问题的建议:

The following will keep on checking up on the user to see whether or not they need advice regarding a question:

def doTheyNeedAdvice(advice):
    while raw_input("Do you need advice? ").lower() == "no":
        pass
    print (advice)

print "How old am I?"

doTheyNeedAdvice("I am old enough")
